William Denison Lyman,
The Columbia River: Its History…
(1909)
“ Throughout the entire Pacific North-west the soil is of extraordinary fertility. It is largely of volcanic dust as fine as flour and seems to contain the constituents of plant life in inexhaustible abundance. Even in the arid belts of Eastern Oregon, where to the eye of the stranger the appearance is of a hopeless waste, those same elements of plant food exist, and with water every manner of tree or vine or flower bursts quickly into perfect life. The climate of the Columbia Basin is a puzzle to the stranger, but in most of its aspects it quickly becomes an equal delight. ”
